Abstract

A process for freeing and concentrating the hydroxylic compounds from marine oils comprises alcoholysing a marine oil with a lower aliphatic alcohol containing 1-3 carbon atoms, dissolving the alcoholysis product in a nonpolar solvent, contacting the said solution with a polar solvent immiscible with the non-polar solvent and recovering the hydroxylic compounds from the polar phase. The alcoholysis is preferably carried out in the presence of an alkaline catalyst and an excess of the alcohol. Suitable non-polar solvents include herring or dogfish liver oil and hexene, and preferred polar solvents are lower aliphatic alcohols containing up to 30% water. It is particularly preferred to use the anhydrous form of a lower aliphatic alcohol as the alcoholysing agent and the same alcohol, containing some water, as the polar solvent, methanol being particularly useful. Specified hydroxylic compounds include Vitamin A, selachyl, chimyl and batyl alcohols.
